At the time another company called Telebit had a 9600 bps protocol called PEP that was totally incompatible with HST. It was also quite popular. But that was back when anybody could by two identical modems and they would interoperate. However, with 56K you can't do that. If both ends of the connection are running a USR 56K modem it will not be possible to get any faster than 33.6kbps.
